Phys.org / Dense, dark forests in Europe are a modern phenomenon
For over 20 million years, the landscape of Europe has been a tree-rich mosaic of grasslands, scrubs and more or less open woodlands with an abundance of wildflowers. This is the conclusion of a new and comprehensive study ...
Phys.org / Microplastics and nanoplastics in urban air originate mainly from tire abrasion, research reveals
Although plastic particles in the air are increasingly coming into focus, knowledge about their distribution and effects is still limited. Chemical analyses from Leipzig now provide details from Germany for the first time: ...
Phys.org / AI cracks Roman-era board game
A smooth, white stone dating from the Roman era and unearthed in the Netherlands has long baffled researchers.
Phys.org / Superfluids emerge in 2D moiré crystal formed from time, study predicts
Conventional crystals are materials in which atoms arrange themselves in repeating spatial patterns. Time crystals, on the other hand, are phases of matter characterized by repeating motions over time without constantly heating ...
Phys.org / With Evo 2, AI can model and design the genetic code for all domains of life
The DNA foundation model Evo 2 has been published in the journal Nature. Trained on the DNA of over 100,000 species across the entire tree of life, Evo 2 can identify patterns in gene sequences across disparate organisms ...
Tech Xplore / How an overlooked electrostatic force could drive the motor of the future
When we hear about moving objects with electricity, most of us imagine a "pulling force." Positive and negative charges attract each other, drawing objects together. It is natural to think that this attractive force—known ...
Phys.org / A Plan B for space? On the risks of concentrating national space power in private hands
Private companies are no longer peripheral participants in U.S. space activities. They provide key services, including launching and deploying satellites, transporting cargo and astronauts to the International Space Station, ...
Phys.org / Study finds 77% of US national parks are highly vulnerable to climate change
National parks in the United States represent a treasure trove of natural, historical, and recreational landscapes, but their health is at risk. A comprehensive new study on the climate-change vulnerability of national parks, ...
Medical Xpress / How gut bacteria and diet can reprogram fat to burn more energy
Scientists at City of Hope and the Broad Institute and Keio University have discovered how specific gut bacteria work together with the diet to flip a metabolic switch—transforming energy-storing white fat into calorie-burning ...
